UK Variant Landscape (By Level)
Data updated 22-06-2025 at 07:17 using the latest COG-UK data with variants assigned using Nextclade.
UPDATED METHODOLOGY: 06/08/23
Now looking at just 2 spike mutations, L455F & F456L (The FLip mutations). See this tweet by
Yunlong Richard Cao for more details.
Mutations at position 478 still seem relevant right now, but the 'FLip' mutations seem to be where things are headed.
This table contains some provisional data and is subject to change - indeed may be completely wrong in some cases.
